The word geo comes from the word "earth" and thermal from the word "heat."
Geothermal energy is heat from within the Earth. We can extract or get this energy by getting the heat or steam. It is then used to heat buildings, generate electricity, etc.
It is generated inside the earth's core. Temperatures hotter than the sun accumulate inside the earth's core.
Where there is a lot of geothermal energy are called geothermal reservoirs. Such forms of reservoirs include volcanoes, hot springs and geysers.
Earth's geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, from volcanic activity, and from solar energy absorbed at the surface.
We can use geothermal energy to produce heat to heat our homes and businesses, and to pump hot steaming water directly into homes and/or businesses.
